Cannot change KDM greetings

It's easy and intuitive to change the KDM greetings for the default KDM theme. But the same thing is impossible for the SuSE KDM theme (SuSE 9.3). This very nice KDM theme looks like a GDM and the default bootsplash graphics, but I cannot change the greet ings. The settings in the Control Center and YaST sysconfig editor have effects only if I use the KDE's default KDM theme.
